    Phoronix: Linux 2D Performance: Nouveau vs. NVIDIA

    After last weekend delivering 30-way Intel/AMD/NVIDIA 2D Linux benchmarks this weekend I have some results comparing the GeForce GPU performance for 2D operations between the open-source Nouveau driver and the closed-source proprietary NVIDIA Linux driver.

    Nouveau is only for experimental and development purposes. It is unable to provide acceptable quality for a regular user with modern hardware. And if you look the radeon/radeonsi situation that is still far from complete experience, I think nouveau will be in good shape in 7-10 years if ever!

      Well, as soon as reclocking will work, nouveau will be on par if not better in 2d performance with the blob.

        Hmm, the nouveau results sure are flat in most tests...

          Why is Nouveau so slow? Is the real reason lack of reclocking support?

            No.

            Lack of reclocking is making newer cards indeed perform worse than their full potential if you compare them to their predecessor.

            Most Radeon cards work nicely.

            As for nVidia cards, feel free to stick with the blob.

              Reverse-engineering Nvidia's unacceptable blackboxes isn't a trivial task. Nouveau developers are doing an outstanding job out of no documentation and no support.

                Except for the gtkperf tests, these results are actually very nice considering the lack of reclocking. Seriously if nouveau can gain reclocking for all chips, this will be huge for them. It'll give us a solid understanding of where they're really falling behind.

                  You don't understand what I mean. To put it straight. in 7-10 years if ever, might be able to load properly a game like Metro LL.

                  I have a RV630 and half of the games have corrupt graphics and performance is like 20-40% of Windows.

                  Real games like Metro LL, Wargame E.E., Portal, HL2, FM2014 etc not Xonotic-like games.

                  I am forced to deal with Windows malware/viruses and suffer antivirus/antimalware software performance impact, just to be able to play light games like Portal or FM2014 in my HTPC. AMD Radeon drivers for gaming in comparison to Windows 13.9 Catalyst are SHIT!

                    I do. We are talking about Nouveau here I think...

                      RV630 is the exception, though, not the rule. It's a strange little card that came out while AMD wasn't supporting the OSS drivers, and has never been supported properly. AMD is focusing their work on getting new cards to run rather than going back to work on the old cards. Get something from the Evergreen generation, and you'll have a completely different experience.

                        I wonder when Nvidia fixed the Xrender implementation in their driver. It used to be unusable. I just tried kwin in xrender mode, and it worked! It used to make all desktop effects run at 1-2fps, where nouveau (and software rastering in X11) could do 30.

                        I wonder if xrender was fixed at the same time as xrandr; a few months after Linus had shamed nvidia for their linux support.

                          I've seen similar claims before. What is this assessment based on?

                              Thanks. I remember seeing that but since there are questions on whether it will scale and 2 of the 3 used cards are so old they are practically irrelevant it didn't make a huge impression on me.

                              I'd actually love to see another test like that. After all things are bound to have changed after 1,5 year (?).
